NOTICE
It is required that the brine circuit is filled BEFORE the brine pump test run is
activated.
There are 2 ways to perform an air purge:
▪ with a brine filling station (field supply),
▪ with a brine filling station (field supply) in combination with the unit's own brine
pump.
In both cases, follow the instructions included with the brine filling station. The
second method should only be used when the air purge on the brine circuit was
NOT successful using only a brine filling station.
In case a brine buffer vessel is present in the brine circuit, or if the brine circuit
consists of a horizontal loop instead of a vertical borehole, further air purging may
be required. You can make use of the 10 day brine pump operation. See
"11.4.6 To start or stop 10-day brine pump operation" [4 208] for more
information.
To perform an air purge with a brine filling station
Follow the instructions included with the brine filling station (field supply).
To perform an air purge with the brine pump and a brine filling station
Prerequisite: Performing an air purge on the brine circuit was NOT successful using
a brine filling station only (see "To perform an air purge with a brine filling
station" [4 203]). In this case, use a brine filling station and the unit's own brine
pump simultaneously.
1 Fill the brine circuit.
2 Start the brine pump test run.
3 Start the brine filling station (MUST be started within a time frame of
5~60seconds after starting the brine pump test run).

Result: The brine pump test run starts running, starting the removal of air from the
brine circuit. During the test run, the brine pump operates without actual
operation of the unit.
INFORMATION
For details on starting/stopping the brine pump test run, see "11.4.4To perform an
actuator test run"[4204].
